Lasers are now used in every aspect of dentistry from detecting cavities to treating gum disease. When an office does “laser dentistry” it includes some or all of these treatments. The greatest benefit of laser use is allowing the dental team to provide less invasive dentistry. Procedures done with lasers tend to cause less post-operative pain, bleeding, and swelling. They also promote better healing in gum disease therapy because the laser kills bacteria in the treatment area and stimulates the gums.
